Most Flexible PCB manufacturers recommend 1.57mm (0.062 inches) as the standard PCB thickness size. This is the thickness that was used for manufactured bakelite sheets in the early days of PCB fabrication.

However, Flexible PCB manufacturer still offer standard thickness in; 0.4 mm (0.016 inch), 0.5 mm (0.020 inch), 0.6 mm (0.024 inch), 0.8 mm (0.032 inch), 1.0 mm (0.04 inch), 1.2 mm (0.047 inch), 1.5 mm (0.062 inch), 1.6 mm (0.063 inch), 2.0 mm (0.079 inch), 2.3 mm (0.091 inch), and 3.175 mm (0.125 inch). Ultimately, the right thickness depends on your specific PCB project. 

For instance, PCB projects with less demanding requirements call for a standard PCB thickness of 1.66mm (0.063 inches). This thickness will still offer maximum efficiency in terms of overall cost and leads time. 

There are cases where the standard core thickness and solder mask coating are considered for controlled dielectric applications and controlled impedance. Thus, the effects of the solder mask must be considered as the solder mask decreases the impedance caused by thin traces.
